Whitco Tasman mk3 Security Door Lock.


‘DualSelect’ offers safety and security for all occupants by giving a choice of selecting privacy-lock or deadlock when exiting the home. Turning the key to the first selection engages the privacy lock, which offers security from the outside whilst allowing occupants inside to safely exit using the internal privacy snib. The second selection engages the deadlock, which provides security, but requires the key to unlock the door from inside and outside.
